GeForce GTX 1070 vs GeForce GTX 295

Intro

Compare all of that to the GeForce GTX 295, which has a GPU core clock speed of 576 MHz, and 896 MB of GDDR3 RAM running at 999 MHz through a 448-bit bus. It also features 240 Stream Processors, 80 TAUs, and 28 ROPs.

GeForce GTX 295		92160 Mtexels/sec
	Difference: 88560 (96%)

Pixel Rate

The GeForce GTX 1070 is quite a bit (about 199%) faster with regards to FSAA than the GeForce GTX 295, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 1070		96384 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 64128 (199%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
